Lentivirus plasmids will be shipped in 0.5 ml tube, and users are free to amplify. Upon receiving the tubes, keep it at 4 °C till amplification.

Core binding factor (CBF)/RUNX1 is a heterodimeric transcription factor that binds to the core element of many enhancers and promoters. The protein encoded by this gene represents the alpha subunit of CBF/RUNX1 and is thought to be involved in the development of normal hematopoiesis. Chromosomal translocations involving this gene are well-documented and have been associated with several types of leukemia. Three transcript variants encoding different isoforms have been found for this gene.

The following figure is the results of experiments to prove our shRNA performance

(One shRNA sequence was selected for one target in each design)

Non-target Gene-specific shRNA shRNA• shRNA Lentivirus were created to target 10 transcription factors expressed in HepG2 cells.• 64 hrs after infection without antibiotic selection, the target gene mRNAs were down to 28.8% in average of 10 shRNA target (p<0.0001 by paired t-test). 9 out of 10 design shRNA were able to suppress more than 70%, and only one out of 10 shRNA suppressed more modestly about 60%.• Suppression will be greater, when the cells would be cultured longer time with antibiotics selection.

Ten transcription factors expressed in HepG2 cells were selected for this experiment. The lentivirus plasmids expressing shRNA were made for each target gene using our propriety design scheme (One shRNA sequence was selected for one target in each design). Lentivirus was created in 12-well plates using our Lentivirus Production kit, which produces a high titer stable lentivirus solution in 48hrs. HepG2 cells were grown in 96-well palate and infected with each virus including negative control shRNA by adding 50µl crude virus solution into HepG2 cells cultured with100µl culture medium for overnight(16hrs.). The cells were incubated further 48hrs., and harvested for Direct RT real-time PCR. As shown in the right figure, 64 hrs. after infection, target gene mRNAs were down to 28.8% in average of 10 shRNA target. 9 out of 10 design shRNA were able to suppress more than 70%, and only one out of 10 shRNA suppressed more modestly about 60%.
